Technical details
HCL DFXAnalytics version 3.0 and below is vulnerable to information exposure (CWE-200) via internal file path disclosure. The vulnerability exists in the application dashboard, which fails to properly sanitize or suppress verbose error messages, system logs, and debugging output. A remote, unauthenticated attacker can trigger these errors to reveal absolute directory paths and internal file structures of the underlying server. This reconnaissance data can be leveraged to bypass security controls or identify specific locations for secondary attacks, such as local file inclusion or directory traversal. Users are advised to review the HCL security bulletin for patching information.
